Accupro 12181608 Square End Mill 3/16 in 2 Flute Carbide

Product Description

The ACCUPRO 12181608 is a solid carbide square end mill designed for precise milling operations in metal fabrication and machining applications. Built from micrograin carbide, this stub-length tool features a 3/16 inch cutting diameter, a 3/8 inch length of cut, and a 40-degree helix angle for efficient chip evacuation. The two-flute, spiral-flute geometry supports both slotting and peripheral milling. It is centercutting, allowing direct plunge entry into workpieces. Machinists and tool-and-die professionals use this end mill on CNC mills and manual knee mills for ferrous and non-ferrous stock removal.

This end mill is well suited to light-duty profiling, slotting, and contouring in small-bore or tight-clearance areas where a 3/16 inch diameter tool is required. The stub overall length of 2 inches limits deflection, making it appropriate for higher-feed passes in steel, aluminum, and similar materials. The uncoated finish makes it easy to inspect for wear and works across a wide range of workpiece materials without coating compatibility concerns. Single-end configuration means it is replaced rather than flipped when worn.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting design allows direct plunge milling without pre-drilling
• Right-hand cut with right-hand flute direction for standard spindle use
• Stub length minimizes tool deflection in high-feed or interrupted cuts
• Uncoated finish simplifies wear inspection across varied workpiece materials

Compatibility

Designed as a standard shank replacement end mill for CNC machining centers and manual mills accepting a 3/16 inch straight shank tool holder or collet.

Installation Notes

Installation should be performed by a qualified machinist following safe tool-change procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully in the collet or tool holder to the recommended grip depth and torque the holder to the machine manufacturer specification. Verify runout with a dial indicator before beginning a cut to avoid premature tool wear or workpiece damage.
